Definitions

  • a lifting platform that can also be raised and temporarily fixed in the elevator shaft is installed above the machine platform.
  • a group of deflection pulleys is attached to both the lifting platform and the machine platform, wherein a multiply reeved lifting cable is arranged between the group of deflection pulleys of the lifting platform and the group of deflection pulleys of the machine platform in such a way that the machine platform may be raised with the aid of two cable pull devices installed on the machine platform.
  • the lifting platform Before each raising of the machine platform, the lifting platform must be brought to a higher level in the elevator shaft. This is done with the help of a hoist, which is attached to another supporting structure that can be moved and fixed in the elevator shaft and can raise the lifting platform via a lifting cable.
  • the requirement for minimizing the risk of the lifting platform falling can be met with relatively little effort, even if the lifting platform must be positioned in the uppermost region of the elevator shaft that does not yet have any guide rails.
  • This measure ensures that, when a lifting platform that is moving downwards at an impermissibly high speed is stopped by the cable catch device, a lifting platform that is not guided on guide rails does not tip over, but rather maintains its horizontal position. Injuries to assembly personnel and damage to the lifting platform and the walls of the elevator shaft can thus be avoided.
  • a further aspect of the invention relates to an elevator system in an elevator shaft of a building that is in its construction phase, in which elevator system a usable lifting height of the elevator system can be adapted to an increasing height of the building.
  • This elevator system is preferably designed in such a way that it is suitable for carrying out the method described above.
  • the elevator system comprises a machine platform installed in the elevator shaft, which can be raised and temporarily locked along car guide rails, wherein an elevator drive machine having a traction sheave is arranged on the machine platform.
  • the elevator system also comprises an elevator car and a counterweight, which are suspended from the machine platform via suspension means, wherein the suspension means are guided at least over the traction sheave of the elevator drive machine, so that the elevator car and the counterweight can be moved up and down in opposite directions to one another along guide rails in the elevator shaft by the traction sheave via the suspension means.
  • a construction crane 40 is indicated above the protective platform 20 or above the currently upper end of the elevator shaft 2 , with the help of which construction crane the lifting platform 17 can be raised with less effort than with the lifting device 35 , if the construction crane is available when the lifting platform is to be raised.
  • An adaptation of the elevator system 1 to a newly available greater height of the elevator shaft 2 is essentially achieved in that—if necessary—first the protective platform 20 is raised to a higher level. This is usually carried out using a construction crane 40 or a hoist suspended from, for example, a temporarily installed cross member. The lifting platform 17 is then raised with the construction crane or the lifting device 35 and fixed at a height in the elevator shaft 2 which makes it possible to transport the machine platform 10 to the planned new level with the hoist 18 of the lifting platform and to lock the machine platform there.
  • the definition of the installation position refers to the position of the cable pulley level.
  • the cable pulley support 26 with the cable pulleys is fixed to the protective platform 20 , which has been positioned in or on the currently uppermost region of the elevator shaft at the latest when the usable lifting height of the elevator system 1 begins to be adapted to a currently existing height of the building or elevator shaft 2 .
  • the cable catch device 25 . 1 comprises the safety cable fixed point 29 attached to the lifting platform 17 , a load-bearing pulley arrangement 32 coupled to the lifting platform, the cable stop device 30 and the four load-bearing cable portions 31 . 1 - 31 . 4 comprising the safety cable 31 .
  • the safety cable is arranged between the lifting platform 17 and the cable pulley support 26 fixed above the lifting platform in the elevator shaft according to the principle of a block and tackle having the four load-bearing cable portions 31 . 1 - 31 . 4 , wherein a first load-bearing cable portion 31 . 1 of the safety cable 31 is fixed to the safety cable fixed point 29 attached to the lifting platform 17 , and wherein a last load-bearing cable portion 31 . 4 is guided through a cable stop device 30 attached to the lifting platform.
  • the cable catch device 25 . 1 for the lifting platform 17 shown in FIG. 2 solves the problem of ensuring that, on the one hand, the catching force resulting from a catching process passes through the center of gravity S of the lifting platform and, on the other hand, that a free space extending upwards from the center of gravity S space can be realized.
  • this object is achieved by the safety cable 31 —with reference to an imaginary reference plane extending vertically through the center of gravity S of the lifting platform 17 —is guided from a safety cable fixed point 29 on the lifting platform vertically upwards to a vertical first deflection pulley 27 .
  • the lifting platform 17 is shown without the lifting device 35 shown in FIG. 1 , either because the lifting device has been dismantled to enable a crane cable to be coupled to the lifting platform for raising the lifting platform 17 , or because there is no lifting device at all, since it is intended to raise the lifting platform exclusively with the construction crane 40 .
  • FIG. 3 shows a side view of a part of the elevator system 1 according to FIG. 1 in the currently topmost region of the elevator shaft 2 on the left-hand side, and a section A-A through this region on the right-hand side.
  • the lifting platform 17 is equipped with the cable catch device 25 . 1 according to the first embodiment shown in FIG. 2 .
  • FIG. 3 shows the elevator system with the lifting device 35 indicated in FIG. 1 , which is used to raise the lifting platform 17 , because no construction crane is present, or if the construction crane is not available within a reasonable time at the time of the adaptation of the usable lifting height of elevator system.
  • the elevator system 1 according to FIG. 3 which is equipped with the lifting device 35 , additionally has a lifting cable deflection device 36 , a cable pull device 37 , a lifting cable 38 and a lifting cable holder 39 .
  • the lifting cable deflection device which comprises at least one lifting cable deflection pulley 36 . 1 , is advantageously fixed to the protective platform 20 described in connection with FIG. 1 in the region of the passage opening 21 present therein.
  • a first load-bearing portion of the lifting cable 38 is fixed to the lifting platform 17 by means of the lifting cable holder 39 . From this lifting cable holder, the lifting cable is guided vertically upwards to the at least one lifting cable deflection pulley 36 .
  • FIG. 4 shows a side view of a part of the elevator system 1 according to FIG. 1 in the currently topmost region of the elevator shaft 2 on the left-hand side, and a section A-A through this region on the right-hand side.
  • the lifting platform 17 is equipped with a lifting device 35 —as already described in connection with FIG. 3 .
  • the elevator system according to FIG. 4 is equipped with a cable catch device 25 . 2 according to a second embodiment.
  • the cable pulley support 26 of the cable catch device 25 . 2 is equipped with only four vertically arranged deflection pulleys 28 . 1 - 28 .
